Our products enable companies large and small to mix and match AWS, Microsoft Azure, Google Cloud, and other clouds as well as on-premises environments, easing their ability to deliver new applications for their business.
At HashiCorp, we have used the Tao of HashiCorp as our guiding principles for product development and operate according to a strong set of company principles for how we interact with each other. We value top-notch collaboration and communication skills, both among internal teams and in how we interact with our users.

About the Role:
On the Consul team, we help organizations automate network configurations, discover services, and enable secure connectivity across any cloud or runtime. The customers and large community of users of our tools are operators, infrastructure engineers, and software developers that encounter novel performance, scaling, and usability challenges that we help them solve.
Consul started as an infrastructure management tool for service discovery and health checking, and has evolved to become a full-featured service mesh. You’ll be an active contributor to the service mesh ecosystem, following new developments in emerging technology and competitive offerings, looking for opportunities for product differentiation, and rethinking product architecture to meet new global scale and organizational demands.

Make a difference in an innovative team and build a world class big data research platform.
Numus is a global group of quantitative, engineering, and blockchain experts. We are contributing to shape the future of applied decentralized finance. We are a native global and decentralized team with an office presence in Zug, Switzerland. We combine extensive and diverse experience from the Crypto, Quant, Tech and Finance worlds but are bound by a shared passion for sharing ideas, learning from each other and solving new problems together.
Are you keen to work in a startup where your ideas, experience and willingness to find creative solutions – and not your title – makes a difference?
You will help design, create and improve our central automated trading platform, written mostly in Go. You will help to make our architecture even more secure, resilient and fault-tolerant while maintaining a modular, well-tested architecture with simple and elegant code, focussed on speed and latency. A good line of code for you is the one which wasn’t written. You see infrastructure as code and see the deployment and monitoring as an integral part of your work, DevOps-style. You rather try to use a AWS cloud service instead of running your own piece of infrastructure or code. Security is always on your mind, and you’re maybe always a little bit too paranoid. You will also help research developers to port their Code to Golang and maintain code quality. You love to explore new state-of-the-art tools and discuss them with your team. Contributing to Open Source projects (e.g. modules to connect to exchanges) is an important part of your work as well. You’re super detail and quality oriented and love to work in a team where most problems haven’t been solved so far – so we highly value creativity to find solutions.

Rumble brings together the best of IT, security and networking technology to deliver amazing network discovery and asset inventory capabilities for modern enterprises.
An accurate network inventory is a fundamental building block of all security programs, yet most inventory products do a poor job of network-based discovery because they only see it as a stepping stone to the “real” product features. Legacy products work by sending sensitive credentials to every asset on the network and fail to handle today’s hybrid environments. Without a solid inventory, most companies struggle with attack surface reduction, network management, and incident response.
Rumble Network Discovery is a product of Rumble, Inc. We are a fully virtual, high-growth startup based in the United States. Our founders each have over 20 years of experience growing companies in the information security industry, including Rapid7, Veracode, BreakingPoint Systems, and PGP.
Rumble has already proven its market fit. Rumble appeals to companies of all shapes and sizes; we have customers that range from museums to Fortune 500 technology companies. We serve the low-end of the market through eCommerce and the mid-market and enterprise segment through inside sales.
We’re building the engineering team to lead Rumble into the future. Our work is a mix of Go development, low-level protocol research, standard web technologies, PostgreSQL, and a mix of cloud technologies and integrations. Our platform is cloud-agnostic, can be self-hosted, and builds from a single repository. We ship daily and focus on incremental delivery with fast turnaround for customer requests and bug fixes. We bootstrapped to product market fit and recently raised a $5m venture capital round to accelerate our growth. The company was cash-flow positive in 2020.
We’re looking for senior engineers that are excited about research-driven product development and want to help build a company focused on happy customers and product-led growth.
We’re searching for senior engineers to grow our team! You will contribute to all stages of development, deployment, support, operations, and product planning. This position reports directly to the CEO today and will split into functional teams once the team expands. This is a growth opportunity for future engineering leadership as well as long-term individual contributors.
Contribute your skills and knowledge to building, supporting, and operating an amazing product experience for our customers.
Learn as you go to understand customer needs, product structure, fingerprinting techniques, and network protocols.
Self-task and coordinate with the rest of the engineering team to move the product forward, solve customer challenges, and keep the platform running smoothly.
Work with customers to identify bugs, understand gaps in product functionality, and flag opportunities for improvement.
Work closely and communicate effectively with functional teams across the company to keep our customer experience aligned with product and sales operations.
A strong track record of building products that customers love.
5+ years of experience in programming-heavy engineering roles with a demonstrated ability to ship quality results, frequently.
Go programming experience is preferred, but if you have deep experience in other languages and are excited about learning Go, we can make that work too.
Extensive experience with web development (HTML, CSS, plain JS) and a solid understanding of the HTTP protocol and the web browser security model.
PostgreSQL database experience, but other SQL database experience is also applicable.
A solid understanding of standard development tools and processes, including Git and issue-management systems.
Confidence working with Linux instances for deployment and diagnostics.
We’re a fully remote company but you need to be located in the US, with US citizenship or permanent residency for healthcare, payroll, and legal reasons.
We offer an extensive set of benefits including:
Competitive salaries and a stock option plan.
Top of the line medical, dental, vision, life and disability coverages with Rumble paying for 99% of the premium.
A flexible vacation policy.
401(k) match program.
To apply for this role, please send your resume and information about the products you have worked on to careers@rumble.run.
We encourage under-represented applicants to apply, even if you don’t think you fit 100% of the criteria (nobody ever does)!
